DPS Beige 4066 Omnidirectional Headset Mic Microdot Connector

4066 Omnidirectional Headset Mic  Requires Microdot Adaptor to Work 

 Resistant to humidity

 Double-vent protection system

 Available in three colors and three sizes

 Modular adapter system fits most professional wireless systems

 
The headset construction is unique. You can detach the mic boom from the headset mount to switch it to either the left or right side and then reattach it. Humidity, often an issue in theatrical applications, is not a problem. This microphone is constructed with a double-vent protection system and a drop stopper on the microphone boom. Also, the materials inside the mic are water resistant. These design elements make it very difficult for the microphone to fail due to humidity.

The microphone’s sensitivity is 6 mV/Pa. This matches the level of the human voice to the general input sensitivity of most wireless transmitters. If powered correctly, the microphone will be able to handle very high sound pressure levels up to 144 dB SPL before clipping occurs.
